Title: Chain gate apparatus
Inventor: KIMURA TOKUJI
IPC: E04H6/42
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To eliminate an unstrained portion of a chain when a garage entrance is opened. SOLUTION: A chain holder 7 which is rotatable in a vertical plane and capable of self-resetting is linked to a hollow columnar body 2 via a second rotational axis 8, and has its end 7b made in contact with a chain 1 from below. When the chain 1 is in a strained state, the end 7b is arranged at a predetermined location separate from the hollow columnar body 2. When the chain 1 is delivered, the strained chain 1 is held as it is, and the chain 1 delivered from the hollow columnar body 2 via a passing port 3 is not moved beyond the end. Therefore, the chain 1 is slacked off between the end and the passing port 3, and when the total weight of the chain 1 positioned outside the hollow columnar body 2 reaches a predetermined weight, the chain holder 7 is overturned, which releases the chain 1 held by the end on the fixed end side all at once.  On the other hand, when the chain 1 is housed, the chain performs self-resetting according to the housing of itself.

IPC: C08F220/10
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a functional-amine-group-containing latex by emulsion- polymerizing an ethylenically unsaturated monomer with N-vinylformamide and hydrolyzing the water-insoluble N-vinylformamide polymer particles with an acid.  
     SOLUTION: A water-insoluble monomer system containing an ethylenically unsaturated monomer desirably vinyl acetate and optionally another ethylenically unsaturated monomer and N-vinylformamide is emulsion-polymerized to form a copolymer. The copolymer is brought into contact with an acid under conditions in which the amide units can be converted into amine groups to hydrolyze the polymer containing units of polymerized N-vinyl-formamide and to thereby produce a functional-amine-group-containing latex. According to the above process, amine parts can be incorporated in the water-insoluble polymer without previously adding a diamine to the latex and therefore undesirable side reactions can be prevented.
